Job Description & Details
This is a heavy-hitting network architecture role focused heavily on Operational Technology (OT) infrastructure where uptime, low latency, and physical safety are non-negotiable. You will act as the technical lead bridging the gap between high-level enterprise WAN strategies and mission-critical industrial environments.
What You'll Actually Be Doing
Expect to spend a good chunk of your week jumping between high-level design (HLD) planning and getting your hands dirty deploying routers, switches, and firewalls. You are going to be building resilient topologies across WAN, data center, and hybrid setups while obsessing over zero-trust security and network segmentation to keep critical OT environments safe. When something breaks, you will lead the root cause analysis on gnarly, multi-domain failures under pressure.
The Core Tech Stack
You need absolute mastery over core networking fundamentals—TCP/IP, the OSI model, and dynamic routing protocols like BGP and OSPF are daily requirements. On top of standard enterprise routing, you must have solid exposure to SD-WAN architectures and modern automation scripting using Python or PowerShell. If you have played with Infrastructure-as-Code (IaC) tools like Terraform or Ansible, or have background in industrial OT environments like SCADA, you are going to feel right at home here.
Interview Expectations
They are going to test your mettle on failure domain isolation and advanced traffic engineering. Expect a grilling on how you would design a highly available hybrid network architecture with strict redundancy paths and zero single points of failure. They want to see how you troubleshoot complex latency spikes across segmented WAN domains while maintaining strict adherence to industrial security compliance.
Application Advice
Your resume needs to heavily feature your large-scale network architecture projects, specifically highlighting quantitative metrics around uptime improvements and scale. Make sure acronyms like BGP, OSPF, SD-WAN, HLD/LLD, and Python automation are explicitly visible to clear the ATS keyword filters. Frame your past roles around ownership of mission-critical infrastructure rather than routine maintenance tasks.
